HA no more accessible and just ios error in the log

hello everyone
I recently tried to configure the ios app for device tracking and also add ios: component in the configuration.yaml.

Unfortunately I cannot access my ha page anymore, getting the following error “Unable to connect to Home Assistant. Retry”

Weird thing is that in the log file I just have
2019-01-13 22:48:23 ERROR (SyncWorker_7) [homeassistant.components.notify.ios] The notify.ios platform was loaded but no devices exist! Please check the documentation at https://home-assistant.io/ecosystem/ios/notifications/ for more information

which seems to relate the issue to the ios component. Of course I tried to remove it from the configuration file already. No luck there
Other weird thing is that checking the config in the IDE, gets me no error

please help…
